We guess Mayor Michael Bloomberg tired himself out marching in the Rockaways St. Patrick's Day Parade on Saturday. How else to explain why he didn't march in the St. Pat's for All Parade in Sunnyside on Sunday?

The mayor didn't give any explanation as to why he skipped out on marching in the parade on Sunday; after all he was there before the parade to deliver some remarks, wave to the marchers, and kiss some babies along the route. (Okay, we made that last part up.)

Maybe it didn't have anything to do with him being all tuckered out, but had more to do with the chilly reception he got on Saturday from the folks in the Rockaways. As the mayor marched, people watching the parade booed Hizzoner as he passed.

They were presumably upset about the way the city has handled the response to Hurricane Sandy, and weren't shy about letting the mayor know it. But would that really dissuade the mayor from marching on Sunday?

After all, it's not like Sunnyside was hit particularly hard by Sandy, so we can't imagine that there would be any lingering ill will toward Bloomberg. We're pretty sure he was safe from heckling and jeering on Skillman Avenue.

Maybe he really is suffering from parade fatigue, and simply saving himself up for the big St. Patrick's Day march up Fifth Avenue in Manhattan?

Either way, surely the mayor expected that things might get a little dicey out in the Rockaways. After all, it's not the first time he's found himself on the wrong end of the ire of Sandy-devastated residents on a visit to the peninsula.

Shortly after the storm, the mayor took a tour of the Rockaways and received a similar reception, most of it caught on television cameras.

At a press conference in Long Island City on Monday, the mayor had this to say about his hecklers when asked about the booing:

"Look, these are people who are frustrated because they've been dealt a bad hand by God, but I will say there's been an awful lot of very generous people—we've collected something like $55 million from private sources. We've made enormous progress. And I understand, people are frustrated. They're not back to where they were. But I think we have to say 'thank you' to those that helped, appreciate what was done, and we'll get a lot done more. We plan to have our beaches open on time. We're gonna rebuild as much as we can as quickly as we can. And I understand the frustration. And if you take it out by booing the mayor, OK, so what. I mean, you know, it was still a nice parade."
